Application led Febluary'lG, 1918. Y Serial No. 217,647;

To all lwlw/m, t may concern:

Be it known that we, EARL E. SIMMs and GUsr W. JOHNSON, citizens of the United States, residing at Longmont, in the county or' Boulder and State otl Colorado, have invented certain new and useful Improvements in Automatic Carriages for Stackers, of which the following is a specification.

The` present invention has reference to certain improvements in hay stackers and it is the principal object of the invention to provide a novel form` ot carriage for supporting hay stackers and like forms o1 elevating devices, for automatically shifting or advancing the same vin order that the hay or straw handled-thereby will be evenly spread during the stacking operation, thereby lengthening the stack so formed and dispensing with the labor and Vresultant eX- pense of men, who have, heretofore, been arranged upon a stack being Aformed for evenly spreading the hay or straw subsequently to the delivery of the same thereonto. Y

The invention consists, furthermore, in the novel arrangements and'combinations of the parts of the device, as well as in the details of construction of the same, all of which will be more fully described in the following specilication, and then finally embodied in the clausesof the claims, which are appended to this specification and which form an essential part of the same.

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a top plan of the improved loader,

Fig. 2 is a side elevation ofthe same,

Fig. 3 is a-fragmental transverse section therethrough,

Fig. 1 is a fragmental-dctail in section 'showing the mounting of the carriage,

Fig. 5 is a side elevation of the novel sheave wheel, Y

Fig. 6 is a transverse section through the same, and

Fig. 7 is a fragmentary detail in perspective of the carriage mounting. 1

Having more particular reference to the drawings, in connection with which like rei-'- `erence characters' designate corresponding parts throughout the several views of the drawings, 1 represents the base of our improveddevice, the same, obviously, comprising a substantially rectangularly shaped :frame rendered portable by the provision of Vthe adjacent end cf the wheels generally indicated by the numeral 2 mounted on suitable axles or like bearings secured to said base; it being noted in this connection, that the forward wheels of the base are dirigible to permit the guiding of the same.V Tracks 3 are secured to the upper faces of members of the base 1 and receive therein rollers et secured by brackets 5 to a carriage Gat dilerent points, preferably adjacent the various Vcorners of the same. On the transverse elements of the carriage G, we mount, in suitable bearings, a plurality of roller bearings designated lby the numeral 7 said bearings being so disposed as to permit the mounting oi a. circular turn-table 8 thereon, which turn. table, as will be understood, has a suitable way or track Qformed uponthe under surface thereof for receiving the upper portions of the bearings V7 therein in order that lateral displacement. of the turntable will be prevented.

A stacker indicated in` its entiretyby the numeral 10 is liXedly niounted" on the turntable 8 and as will be understood, serves as means for elevating the hay, straw, or other matter being handled thereby to a certain point, whereupon, it is discharged onto'the stack being formed. In this connection, we desire to have it clearly understood that variousrforms of stackers may be arranged on the turn-table 8, such as conditions may dictate; this structure, manifestly, forming no part of the invention.

Extending longitudinally of the intermediate portion of the base sides and carriage is a screw threaded shaft 11, one end of said shaft being rotatably supported in bearings 12 lixedly mounted upon the transverse pieceadjacent one end of said base, while the remaining end of said rod is swivelly connected as at 13 withl a transversely disposed tie-rod 14 having its opposite ends engaged with the side portions of the base 1. To effect connection between the carriage 6 and the screw threaded shaft, there is mounted upon the under side of one or' the end or transverse pieces of said carriage, a boxing 15, which as will be understood, is internally screw threaded and receives the shaft 11 therethrough.

Mounted in bearings 12', is one endof a power transmitting shaft 16 carrying4 a bevel gear 17, which gear as will be noted, meshes with similar, but smaller gear 18 keyed to screw threaded. shaftthe parallel longitudinal` v28 v upon leaving when the cable vsecured to one side of the base adjacent the end thereof and' carries a sheave wheel Q0 thereon, which sheave wheel has idlers 21 rotatably mountedin bearings on each end thereof.

VArranged on or formed integralwith the sheave wheel 2() are oppositely disposed bracket arms 22, which bracket arms receive ivot pins 23therethrough` carrying pawls 22k Ratchet elements fzfare arranged'upon t-he opposite sides of the sheave wheel'adjacent the central or hub portion of the same 'and are: adapted to he engaged, at times, by the pivotal pawls 24. Toeife'cta positive connection between the several ratchets` and their'respective pawls, 4springs 24 are engaged with the pawls and serve to normally move the same intoV engagement with'y the' teeth of the ratchetE elements 25. Openings 26 may be andf preferably are formed n the web portion of the sheavve wheel while other openings Q7 are formed in the several pawls and are adapted 'toi receive set screws therethrough, these; set screws, obviously, engaging in thek openings 26 whereby to permitv securingk of' the same in inoperative positions;

As will be understood, the stacker 10'I is provided with a Vhoisting cable' 28', which cable has one end connected to' the load handlingA mgans whilel the remainingV end is connected to a suitable source of power7 whereby the loadvhandling means will be elevated and lowered asd'esired. The cable y the 'stacker is passed through suitable guide elements 29v secured to the base 1 andt is passed under rand over Vthe idiers 21 and 'um shave when 2o. Thus,

when the cable is lmoved to its' connection with'thesource of power, rotary motion will be imparted to the sheave WheelQOand hence tothe power transmitting shaft 16.

The operation of the device maybe re viewed as follows: To cause the carriage G to be automatically moved forwardly ofthe base 1' subsequent yto the discharge of a load of hay, one of the pawls 24 is moved into engagement with' its respective ratchet by disengaging the screw 27 therefrom. Hence, 28' is pulled toV cause elevation of the load handling means,l the sheave wheel 20 will berotatedv i'nl a direction such as will' permit the pawl 24" toridej idly over the variousteeth` of the ratchet 25. `However, after the: load' has been 'released from the load handling mea-nsand thel samev is being" returned# to its lower positionl on` the stacker, the cable' 28 is of course movedin a reverse direction and in consequence', causes reverse rotation of the slieave' 'wheel 20, whereupon' said pawl 24 is engaged with one of the teeth of the ratchet 25,-ther'eby effecting connection between the shea've wheel and the power transmitting shaft 16 andcaus'in'g rat-chet the beveled gearing 17 and 18 to be rot-ated., thereby rotating` the screw threadedY shaft 11 sufficiently to cause the carriage 6 to be automatically shifted to a position'laterally or tO one side of the load last discharged from the stacker. In this way, when afseconddoadV=- is discharged from the stacker, it will be arranged 'adjacent the load first discharged and by consequence, will cause the hay 0r other matter to be evenly spread orV distributed, thereby. permittingthelengtheningV of thek stack 'and dispensing withconsiderable labor and expense.' After the carriage G'hasbeenmoved to the extent its travel ofthe base 1 it thenbecomesnecessary tov return the s'amejtof-its normal or ofV starting position. To efectsuch return of Y the carriage, the remaining Ip'awli 2a' is' engageidv withits respectiveratcfhet while the first mentioned pawl' is disengaged Vwith its They teeth olfV the second ratchet wheel extend` in an oppositedi'rection to the first ratchet wheel and 'therefore the transmission of powerjtfo the shaft* 11 is reversed and thus returns thercarr-iage and the stacker-in a stepeby-steplnianner to its normal or startingposition. Itis of course understood that during the 'returnf ofV the carriage the movementl will be imparted during the 'raising of the:l load handling means insteadoffduring the lovve'ringv of the same. '-Gbviouslly.,v in thismannerl, Ythef c'a'rriage and sta-cker may be moved backfand forth upon the'base '1V for any; number of times as desired,ltherebyv allowing asta'ck to'be efectually built. To renderthecan riage immovable, if, isfonlfyY necessary tord-isen'gage each ofl the pawlsfQLL-from' their respectiver atc'hets, whereupon 'the' sheave wheel QOwill rotate'id'ly upon movement of' the "cab'le128. i 'A n When desiring to lI'novefourimproved device from field to field, the portable'base l is hitched to suitable 'draft meansfand the' turn-table Sv is rotated to cause: the stacker 10' to be arranged endwise thereon, thusv pei'- mittingthesame to be drawn freely.' through gate ways or other'- s'imilar passages. 'nfthis connection, it is to be understoodl that various forms' of means` maybe' employed'Y for locking thev turn-table inl an adjnsted 'position topermit the voperation of the same.

Manifestly` the constructioni'shown 'is'capable of considerable*modification, and such modification as is within the scope of our claims, we consider withintherspirit of our invention.
